Along with the fact no drilling or custom machining is needed, one of the unique features with these systems is there is no hard lines needed to be bent! NOS switched over to flexible plastic n2o & fuel lines which allow you easily run lines even in the tightest of places. Installation costs on these systems should be considerably less then any conventional nitrous system, but overall costs will probably be the same due the almost outrageous prices on the systems.
